Design And Research On Route Protocols Based On Reliability

AODV, as a typical on-demand route protocol in WSN, has the advantages of simplicity of the operation, on-demand route, lack of the route loop and excellent scalability. However, there is only one available route in the course of the data session, the transmitting data will be simply dropped when this route switches off. So the performance and the communication quality of the network will be drastically impacted. To deal with the disadvantages of AODV, an improved protocol based on AODV called FS_AODV was brought forward in this article. FS_AODV reduced the routing overhead incurred in recovering from route breaks, by using secondary paths. It provided all the intermediate nodes on the primary path with multiple routes to destination. Simulations results using NS-2 confirmed that FS_AODV performs better than AODV. It has high reliability.
